OK, let's work through this together. We're starting with 168 and we're going to multiply it by 46, which means we add 168 to itself 46 times.
Step 1: 0 + 168 = 168
Step 2: 168 + 168 = 336
Step 3: 336 + 168 = 504
Step 4: 504 + 168 = 672
Step 5: 672 + 168 = 840
Step 6: 840 + 168 = 1008
Step 7: 1008 + 168 = 1176
Step 8: 1176 + 168 = 1344
Step 9: 1344 + 168 = 1512
Step 10: 1512 + 168 = 1680
Step 11: 1680 + 168 = 1848
Step 12: 1848 + 168 = 2016
Step 13: 2016 + 168 = 2184
Step 14: 2184 + 168 = 2352
Step 15: 2352 + 168 = 2520
Step 16: 2520 + 168 = 2688
Step 17: 2688 + 168 = 2856
Step 18: 2856 + 168 = 3024
Step 19: 3024 + 168 = 3192
Step 20: 3192 + 168 = 3360
Step 21: 3360 + 168 = 3528
Step 22: 3528 + 168 = 3696
Step 23: 3696 + 168 = 3864
Step 24: 3864 + 168 = 4032
Step 25: 4032 + 168 = 4200
Step 26: 4200 + 168 = 4368
Step 27: 4368 + 168 = 4536
Step 28: 4536 + 168 = 4704
Step 29: 4704 + 168 = 4872
Step 30: 4872 + 168 = 5040
Step 31: 5040 + 168 = 5208
Step 32: 5208 + 168 = 5376
Step 33: 5376 + 168 = 5544
Step 34: 5544 + 168 = 5712
Step 35: 5712 + 168 = 5880
Step 36: 5880 + 168 = 6048
Step 37: 6048 + 168 = 6216
Step 38: 6216 + 168 = 6384
Step 39: 6384 + 168 = 6552
Step 40: 6552 + 168 = 6720
Step 41: 6720 + 168 = 6888
Step 42: 6888 + 168 = 7056
Step 43: 7056 + 168 = 7224
Step 44: 7224 + 168 = 7392
Step 45: 7392 + 168 = 7560
Step 46: 7560 + 168 = 7728

So, 168*46 = 7728
